FIGURE 1. Line drawings of Hornellobothrium gerdaae n. sp. (A) Whole worm. (B) Scolex. (C) Mature subterminal proglottid; arrowhead indicates
level at which section in Fig. 6A was taken. (D) Mature terminal proglottid; arrowhead indicates level at which section in Fig. 6B was taken. 
FIGURE 6. Light micrographs. (A) Cross section of mature proglottid of Hornellobothrium gerdaae n. sp. through testes at level between ovary and
cirrus sac. (B) Cross section of mature proglottid of H. gerdaae n. sp. at level of ovarian bridge. (G) Scolex of H. gerdaae n. sp. showing size of apical organ. Abbreviations: AO, apical organ; O, ovary; OC, ovicapt; T, testis; UT, uterus; V, vitelline follicle; VA, vagina; VD, vas deferens. 
FIGURE 3. (A–I) Scanning electron micrographs of Hornellobothrium gerdaae n. sp. (A) Scolex and laterally expanded immature proglottids (i.e.,
hood); small letters indicate location of details shown in F–I. (B) Scolex; small letters indicate location of details shown in C–E. (C) Distal bothridial
surface with lingulate to gladiate spinitriches and acicular filitriches. (D) Proximal bothridial surface with denser lingulate to gladiate spinitriches and
acicular filitriches. (E) Scolex proper anterior to bothridia with acicular filitriches. (F) Laterally expanded immature proglottids (i.e., hood) with small
scolopate spinitriches, slightly enlarged along posterior proglottid margin. (G) Posterior proglottid margin with small scolopate spinitriches. (H)
Anterior proglottid with small gladiate spinitriches. (I) Proglottid surface with capilliform filitriches.
